Universal Best Price / Vol & Unit Sorter

Calculate true unit pricing, highlight retailer price glitches, and sort items by price per volume or roll across shopping sites.

Find the real deals while shopping online! Stop getting fooled by deceptive bulk sizes, confusing multipack math, or broken retailer unit prices. Universal Best Price / Vol & Unit Sorter calculates the true price-per-volume, price-per-roll, price-per-weight, and price-per-count on online store pages — and lets you reorder product results by lowest unit cost with 1 click. ═══════════════════════════════════════ KEY FEATURES ═══════════════════════════════════════ 1. 🧻 SOLVE THE TOILET PAPER & PAPER TOWEL MATH Is 24 "Mega" rolls cheaper than 30 "Family" rolls? Manufacturers use tricky multipliers ("24 Mega = 96 Regular Rolls") to hide true costs. This extension normalizes paper products into regular roll equivalents so you instantly see true cost per roll (e.g. 200 rolls for $15 is sorted ahead of 1 roll for $5). 2. 🚨 PULSING RED GLOWING BOX ON PRICING GLITCHES Online retailer websites frequently suffer from unit price glitches (for example, displaying a listed unit price of 1¢/100ml when the actual price is $1.12/100ml). When a listed unit price contradicts reality by >15%, the extension highlights the item with an animated pulsing red box and a clear warning banner: "⚠️ Pricing Error: Listed 1¢/100ml ❌ → Actual is $1.12/100ml ✔️" It automatically corrects the sort order so inaccurate listings cannot game your search results. 3. ⚡ ONE-CLICK "BEST PRICE / VOLUME" SORTING Default store "Price: low to high" sorts always show tiny travel bottles or single items first.
